By removing the PCB, we also eliminate an extra layer of electrical resistance, allowing more of the stored energy to reach your device, generating less heat and maintaining voltage under load. The tradeā€‘off is small: you must pair these cells with a quality charger that stops at exactly 4.2V, and only install them in devices that have their own builtā€‘in lowā€‘voltage cutoff.

Removing the protection board also eliminates an extra layer of electrical resistance, which means more of the stored energy actually reaches your device, less is converted to waste heat, and voltage sag under load is reduced. Of course, this design philosophy asks something of you in return: always use a quality charger that terminates precisely at 4.2V, and only install the cell in devices that incorporate their own lowā€‘voltage cutoff.

With a generous 3200mAh capacity, your gear runs longer between charges, while the 9.6A continuous discharge easily handles the current demands of medium-to-high brightness modes without voltage sag. The flat top positive terminal ensures compatibility with multi-cell packs, battery carriers, and flat-contact electronics.

The ARB-L18-3300 is compatible with most Fenix and Streamlight models, as well as many other major flashlight brands. Due to the protection circuit and button top, the battery is approximately 68.5mm long. Some ultra-compact lights with very tight battery tubes may not close properly. Please check your device's battery compartment length before ordering.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan class=\"\"\u003eQ: Can I use this battery for RC cars or other high-drain devices?\u003c\/span\u003e\u003c\/strong\u003e\u003cbr\u003e\u003cspan class=\"\"\u003eA: No. RC cars, drones, and similar high-drain devices require 10ā€“30A or more of continuous current. The ARB-L18-3300's protection circuit limits output to approximately 5A. Using it in such devices will cause the protection to immediately cut off power.

This makes single-cell use much safer, especially in devices without their own battery management.
